How AT&T, Verizon and T‑Mobile aim to end cell phone dead zones

While the idea of being disconnected is still appealing to some, in an information-driven world, most people want to be able to stay in touch — regardless of where they are. That’s why some of the new satellite connectivity options have proven to be so appealing to many U.S.-based cellphone customers.
Having the ability to make phone calls from national parks, check your email out on the lake, or, yes, doomscroll your social media feeds from the middle of nowhere is something that a lot of people want to be able to do.
It’s more than just a convenience. In the case of natural disasters or other personal emergencies, the ability to connect can literally mean life or death.
As great as the potential for always-on, everywhere connectivity is, however, the reality hasn’t quite lived up to the promise. Dead spots are still very much a thing, regardless of what service you have.

That’s why the recent announcement of a potential new joint venture uniting the country’s largest telco carriers — AT&T, T-Mobile and Verizon — to specifically address these issues is so important and so exciting. The basic idea is that these companies recognized that the most practical path to eliminating dead spots is via low-Earth orbit (LEO) satellite technology that connects directly to our devices (D2D). To make it ubiquitous for everyone, however, required a lot of cooperative work to iron out some critical technical details — hence the new effort.

A major challenge involves spectrum — the licensed radio frequencies that wireless carriers use to connect phones to their networks. If your phone is on AT&T, it essentially “listens” to one set of frequencies. If it’s on Verizon, it listens to another, and different areas of the country have different mixes of these frequencies.
The same is true for satellite communications with your phone. The Starlink-powered satellite services that T-Mobile recently unveiled are delivered via T-Mobile’s frequencies, or spectrum, and phones with AT&T or Verizon service can’t “hear” them (unless they add T-Mobile’s T-Satellite offering).

AT&T and Verizon have both aligned with AST SpaceMobile, a Starlink competitor that is building a satellite-to-smartphone network. But again, those signals have to be transferred from the satellite to your phone on the appropriate frequencies. None of these services currently work across carriers.
In the early days of cell phones, there were conceptually similar challenges, because if you went outside the coverage area of your specific carrier’s network, you lost the signal. Roaming agreements between the carriers addressed those issues by essentially allowing your call to jump from one carrier’s towers to another so that your call wouldn’t drop. The new satellite efforts are essentially akin to roaming for satellite services. The carriers can pool together their dedicated satellite-connected frequencies and then allow those shared resources to be used by anyone with a recent-era smartphone when their main coverage disappears. (Most iPhone and Android-based phones sold over the last few years should be able to connect with these shared satellite services.)
The new agreement is also designed to standardize the means by which signals are sent and received from smartphones to satellites, as well as how the signals are handed off between satellite and terrestrial networks. This makes it easier for satellite companies to deliver these services, because they can avoid the kind of special arrangements they currently need to make with each of the carriers. That, in turn, is expected to encourage more companies to provide satellite-based services. While they haven’t announced any specific details yet, Amazon’s new Leo satellite network, for example, might eventually become yet another provider with whom the carriers could choose to work.
Even with the standardization, each of the carriers will be able to (and most likely will) offer different variations on satellite-powered services, just as they now do with their existing land-based networks. Simplifying and standardizing the means by which those services are created and delivered should make them more cost effective.
Of course, it’s also important to note that the three carriers announced this joint initiative just days after the FCC approved the sale of some dedicated cellular spectrum to Starlink and about a week before the SpaceX IPO prospectus talked about the company’s desire to build a Starlink mobile service. Clearly, some competitive dynamics are at play, though the potential benefits of the proposed joint venture exist regardless of any competition. Plus, standardizing technical details would make it easier for Starlink to work with other carriers. In truth, satellite service is not a great match for dense urban areas, inside buildings and other places where we typically use our devices, so the opportunities for a satellite-only service would be challenging.
Combining the capabilities of today’s greatly improved land-based networks with a broader area of satellite-based coverage, on the other hand, should prove to be exactly what’s needed to make “always available everywhere” connectivity a powerful new reality. Whether for life-saving emergency situations or just being able to stay in touch, dramatically reducing dead spots across the entire U.S. — whether in isolated rural areas or pockets of metropolitan sprawl — is something we’re likely going to get used to pretty darn quick.
